1 Claim.

This invention relates to certain new and useful improvements in anemergency light and container therefor, and is particularly adapted forconstruction work or for railroads and embodies a light and itscontainer that can be quickly made available and one which can beproduced at a comparatively small cost.

A still further object of the invention is the provision of an emergencylight having a carbide casing and a container in which the carbidecasing is inserted, and means to retain the latter in fixed resilientposition within the container.

A still further object of this invention is the provision of anemergency light, efiicient'in operation and one that can be quicklyassembled and made ready for use at all times.

A still further object of this invention is the provision of anemergency light and container therefor, which container is adapted to befilled with water and toretain the casing of the light proper in fixedposition therein, and ready for use in any emergency in construction orrailroad work.

With these and other objects in view, the invention consists in certainnovel features, combination and arrangement of parts as will behereinafter more fully described, pointed out in the accompanyingdrawing, and claimed.

In the drawing,

Figure 1 is a vertical, longitudinal, sectional view of the casing andcontainer, with the container partly broken away, illustrating thedevice as made in accordance with this invention;

Figure 2 is a perspective View of the container and casing in fullyassembled position;

Figure 3 is a transverse sectional view, taken on the line 3-3 of Figure1; and,

Figure 4 is an enlarged, fragmentary, sectional view, taken on the line4-4 of Figure 3.

Referring to the drawing, the numeral 5 indicates a casing in the formof a cylindrical shell having a bottom portion 8 and top portion 1, allsoldered or welded together to form an air and water tight casing, asclearly illustrated in Figure 1. ihe bottom 6 of the casing 5 isprovided with an opening 3, through which opening water is admitted intothe casing, the purpose of which will be hereinafter more fullydescribed. The top of the casing 5 is provided centrally with openingsit, which coincide with the opening 8 for the purpose of permitting gasgenerated in the casing 5 to escape therethrough to the atmosremovabletab I I sealed thereto to normally close the opening against air andwater until ripped therefrom by virtue of the handle portion 52.

The openings H1 in the top 7 are normally closed in an air and watertight condition by a cap I3 provided with a handle M to permit the capto be readily removed therefrom, the purpose of which will behereinafter more fully described.

A supporting tube l5 has its lower open end secured around the opening 8in the bottom i of the casing and projects upwardly in a verticalposition within the casing 5. Its upper closed end It is provided withopenings ll which establish a communication between the exterior ofcasing and interior thereof by virtue of th opening 8 and openings 17,the purpose of which will be hereinafter more fully described.

A perforated tube I8 is secured by one end to the interior of the bottom6 of the casing 55 and completely surrounds the member it, extendsupwardly and vertically through the casing 5 and has its upper endsecured to the interior of the top 1 surrounding the openings illtherein. ihe purpose of this tube is to protect and prevent the openingsl1 and 8 from becoming clogged or choked up by the mushy detritus of thespent carbide, as will be hereinafter more fully described.

Surrounding the tube IB, near its central portion, is an annular discl9, and it is secured to said tube in such a manner as to separate thecasing 5 into a gas chamber 2i! and a carbide chamber 25, and the latterchamber has placed therein suitable carbide A.

The diameter of the disc I9 is such as to permit gases formed in thecarbide chamber to pass between its peripheral edge and the interiorwall of the casing and to pass up into the chamber It is also to beunderstood that gases generating in the carbide chamber will pass upthrough the tube [8 into the chamber 23 and through the openings 1 i! ofthe top I.

When it is desired to use the structure de-- scribed, it is onlynecessary to place the casing in a container of water. Prior to placingthe same therein, the tab H and cap l3 are ripped from their respectivecovers by virtue of handles l2 and I4 thereof. Water entering throughopening 8 is forced upwardly through openings ll, out through theperforations of the tube l8 into the carbide A, gas generating thereinpasses up through the tube and around the peripheral edge of the bafilel9 into the chan ber 20, and when suflicient gases are generated inchamber 2i! they pass back through tube out the openings l where theyare ignited at that point.

Now, to provide a container for this emergency light I have provided anopen end receptacle 22 having its bottom fully closed, as at 23, and itsopen end provided with an entrance opening 24 of a diameter slightlylarger than the casing 5. The inturned flange 24, constituting theentrance opening of the open end of the receptacle 22, definitelypositions the casing centrally within the receptacle 22.

To normally center and retain the casing 5 in fixed position within thereceptacle 22, I have secured in said receptacle on its side and'bottomwalls, resilient supporting elements 25, which are secured to the bottomand side walls of the receptacle 22, as at 26, by any fastening elementssuitable for the purpose.

The resilient supporting elements 25 firmly hold the casing 5 in fixedrelation about the central axis of the receptacle 22 and also hold thecasing 5 in proper position with relation to the open end thereof, ascan be clearly seen in Figure 1 of the drawing. The receptacle is alsoprovided exteriorly with a suitable handle 21, which renders the sameportable and permits it to be easily transported from place to place andput in proper position when it is desired to use the same.

And to retain and lock the casing 5 in the receptacle 22, there isprovided a turn catch 28, pivoted as at 29, to the top of the receptacle22, one end constituting a handle and its free end constituting aretaining member to hold the casing 5 against vertical movement withinthe receptacle 22.

The receptacle 22 is to be approximately filled with Water and thecasing 5 fastened therein. When it is desired to use the emergency lightit is only necessary to turn the catch 28, lift the casing from thereceptacle 22, rip the tab H and cap I 3 therefrom, reinsert the casingin the receptacle 22, which submerges it in the water contained therein,refasten the catch 28 and ignite the generated gases emanating from theopenings l 0 of the casing.

The action of this emergency light in operation is practically identicalwith the structures claimed in co-pending applications Serial Nos.124,451 (now Patent No. 2,120,523), 124,452 and 124,453, executed andfiled of even date herewith, the only exception being the container andthe construction of the tube l8.

While I have described one embodiment of the invention, it is to beunderstood that various changes might be made in the construction,combination and arrangement of parts, without departing from the spiritof the invention as claimed.

Having thus described my invention, what I claim as new is:

A portable emergency light and water container therefor, comprising acarbide casing having a water entrance and gas exit therein, removableclosures for the entrance and exit, a perforated supporting tube securedto the entrance and extending upwardly in the casing, a perforatedconveying tube secured to and about the first named tube and having itsfree ends secured to and about the entrance and exit openings, and aportable water container provided with interior flexible means toreceive and retain said carbide casing in vertical position in saidcontainer so that the device may be held against displacement intransit.
